Anchorman Bill O’Reilly has called for a media conference to discuss revealing new photos of teenage star Miley Cyrus that were recently leaked online.

The pictures, which show the 15-year-old Hannah Montana star revealing her lingerie and lounging provocatively on an unnamed boy's lap, have caused outrage in America, where Cyrus is a teen role model.

And Fox News’s O'Reilly is keen to get to the bottom of the scandal and find out why and how the photos were leaked online earlier this week.

He says: "We have so few role models, particularly for little girls in this country (and) she (Cyrus) is the main one. I hate to see this.

"Parents all over the country like this girl because she is clean-cut."

Calling the photos a "teasy, peek-a-boo thing," O'Reilly adds: "She's 14 in these pictures - that is the problem."

But Cyrus has her supporters too. Earlier this week, Entertainmentwise reported about former touring partner Joe Jonas of the Jonas Brothers coming to the pop star's defence. Find out what he had to say here.
